半干旱区厚层基质喷附坡面植被返青对比研究

Comparative Study on Regrowth of Thick Layer Base Material Spraying Slope Vegetation in Semiarid Areas

半干旱区公路边坡植被重建是公路生态环境保护的难点,坡面植被越冬率是坡面生态工程成功与否的一个重要指标。本试验研究依托丹东-拉萨高速公路(内蒙古集宁-老爷庙标段)生态护坡工程,结果表明:喷附时间、坡向、坡度,坡面母质、坡位、冻水浇灌以及喷附基材配比等因素,都会影响护坡植物越冬能力,从而通过试验提出相应的养护措施,以改善高速公路的绿化景观效果。

It is difficult for the protection of ecological environment to rebuilt the vegetation of road in the semi-arid area, the rate of living through the winter is an important index to the success of ecologicalproject. This experiment is based on the Dandong-Lasa Expressway （Jining-Laoyemiao Section in Inner Mongolia）, the results indicate that the factors of spraying time, slope direction, slope, nature of face of slope, slope location, freezing water and the rate of spray base material, can influence the rate of living through the winter of the vegetation of road. So relevant measures are advanced to arrive at improving the effect of green sight of the road.
